How to ensure that pesticide residues in fruits and vegetables do not exceed the standard?

Only a good environment can cultivate healthy food. Is there any testing of the environmental quality of agricultural product bases, including the quality of air, soil and water? In the agricultural product base in Xiaoshan, Jiao Li, a representative of the Provincial People's Congress, raised such a question.

In the past few days, the food safety law enforcement inspection team of the Standing Committee of the Provincial People's Congress has inspected the county and township agricultural product quality inspection centers (stations), fruit and vegetable animal husbandry production bases, agricultural supermarkets, etc., in Tonglu and Xiaoshan, focusing on the inspection of the quality and safety supervision of agricultural products at the source. Xiaoshan: More than 100 people have to supervise 240,000 producers "Insecticides and herbicides have different roles, so they should be classified and placed together.

So that farmers don't get the wrong pesticides. "In an agricultural chain store in Xiaoshan, the inspection team pointed out that pesticides were not specifically classified and placed. Compared with the fast-growing industry, Xiaoshan's agricultural development is not inferior, with a huge agricultural product base, and a huge output of agricultural products such as pork, fish, shrimp, and vegetables.

However, the inspection team found in the investigation that there are about 240,000 households in Xiaoshan agricultural product production supervision objects, more than 130 kinds of products, and the supervision workload is very large, and there are only more than 100 town-level agricultural technicians in the whole region, and less than one-fifth of the agricultural technicians who are full-time engaged in the supervision of the quality and safety of agricultural products. Tonglu: The producer can be found through the barcode Tonglu, which has beautiful mountains and rivers, is rich in honey pears.

The law enforcement inspection team came to the pear professional cooperative in Zhongshan Town, Tonglu, and these pears collected by farmers must be selected and tested, and only those who are qualified can enter the market. The professional cooperative has an agricultural product quality testing room, and the staff will take a few pears from the farmers to test whether the pesticides exceed the standard. In the production workshop, the inspectors saw that each box of pears for sale was affixed with a barcode, through which the origin and producer could be found.

Legal analysis: administrative penalties such as warnings, confiscation of illegal gains, and fines.

Legal basis: Article 2 of the Standardization Law of the People's Republic of China The standards (including standard samples) mentioned in this law refer to the technical requirements that need to be unified in the fields of agriculture, industry, service industry and social undertakings.

Standards include national standards, industry standards, local standards, group standards, and enterprise standards. National standards are divided into mandatory standards and recommended standards, and industry standards and local standards are recommended standards.

Mandatory standards must be enforced. The State encourages the adoption of recommended standards.

Legal analysis: for illegal products, order to stop sales, recover agricultural products that have been sold, and carry out harmless treatment or supervise the destruction of illegal agricultural products; confiscate unlawful gains and impose a fine of not less than 2,000 yuan but not more than 20,000 yuan.

Legal basis: Article 33 of the Law of the People's Republic of China on the Quality and Safety of Agricultural Products Article 33 Agricultural products shall not be sold under any of the following circumstances:

Answer: (1) Running water rinsing plus soaking method. The main pesticides used to contaminate vegetables are organophosphorus insecticides.

Organophosphate insecticides are insoluble in water, and this method can only remove part of the pesticide contamination. However, washing is the basic method of removing other dirt and removing residual pesticides on vegetables and fruits, and is mainly used for leafy vegetables, such as spinach, enoki, leek flowers, lettuce, bok choy, etc. Generally, the surface dirt is rinsed off repeatedly with water, then soaked in water for 15 minutes, and then rinsed with running water two or three times.

Fruit and vegetable cleaning agent can increase the dissolution of pesticides, and a small amount of fruit and vegetable cleaning agent can be added to the pants digging car when rinsing.

2) Running water rinsing and alkaline water immersion method. Organophosphate insecticides decompose rapidly in an alkaline environment, so this method is an effective measure to remove pesticide contamination. It can be used for all kinds of vegetables and fruits.

The method is to rinse the surface dirt first, soak it in alkaline water (generally add 5 to 10 grams of alkaline surface to 500 ml of water) for 5 to 15 minutes, and then rinse with water 3 to 5 times.

3) Peeling method. The amount of pesticides on the surface of vegetables and fruits is relatively large, so peeling is a better way to remove residual pesticides. It can be used for apples, pears, kiwis, cucumbers, carrots, winter melons, pumpkins, zucchini, eggplants, turnips, etc.

4) Storage of the law of nonsense. During storage, pesticides can be slowly decomposed into substances that are harmless to humans. For fruits and vegetables that are easy to preserve, they can be stored for a certain period of time with less pesticide residues.

It is suitable for non-perishable species such as pumpkin and winter melon. Generally, it is stored for more than 15 days. At the same time, it is recommended not to eat freshly picked, unpeeled fruits and vegetables immediately.

5) Heating method. Carbamate insecticides decompose faster as the temperature increases. Therefore, some vegetables and fruits that are difficult to treat by other methods can be removed by heating.

It is often used in celery, spinach, bok choy, cabbage, green pepper, cauliflower, beans, etc. Wash the surface dirt with clean water, put it in boiling water for 2 to 5 minutes to remove it, and then wash it once or twice with clean water.

<> modern agriculture is inseparable from pesticides, and eating vegetables is most afraid of pesticide residues, so it must be thoroughly cleaned before eating vegetables to minimize pesticide residues on vegetables. Do you know how to reduce pesticide residues on vegetables? Let's take a look.

Which vegetables are high in pesticide residues? Serve with Rashen

1.Vegetables with a special flavor have fewer pesticide residues

According to the statistics of China's Agricultural Products Monitoring Center, the qualified rate of pesticide residues in vegetables from low to high is: beans (cowpea, sword beans, etc.), eggplant fruits (peppers, eggplants, etc.), cabbage (cabbage, cabbage, etc.), green leafy vegetables (spinach, oily lettuce, etc.), taro potato root vegetables (potatoes, etc.), onions and garlic, melons (cucumbers, winter melons, etc.), and the highest is edible fungi. In this way, the pass rate of pesticide residues such as cowpea and sword bean is low, so pay attention when buying and eating.

In addition, coriander, fennel, chrysanthemum, etc. have a special fragrance, this spicy flavor is a natural insect repellent, the probability of infection with pests and diseases is low, you can eat it with more confidence.

2.There are relatively few pesticide residues in winter vegetables

If the vegetable pesticide residues are sorted according to the season, they are roughly as follows: summer, spring, autumn and winter. Leafy vegetables in winter and spring and autumn are relatively safe, and pesticides are almost not used because there are few insects. In summer, there are many insects, and most of them are planted in the open air, and there are relatively many pesticide residues.

What we eat is nothing more than vegetables and fruits grown in the open air or greenhouse vegetables, the former is more natural and has a better taste, but it is difficult to control pests and diseases, while greenhouse vegetables can be controlled by physical methods such as anti-poison nets, which have advantages in reducing pesticide residues.

3.Are vegetables with "insect eyes" free of pesticides?

Many consumers believe that vegetables with insect eyes are safer to eat without pesticides. But in fact, the presence or absence of insect eyes does not tell whether pesticides are used or not. Depending on the growth cycle of vegetables, vegetable farmers often spray pesticides at an early stage in order to prevent pests and diseases.

Vegetables with insect eyes that consumers see are often vegetables that have been on the market very closely, and pesticide residues may be higher. So, don't blindly assume that vegetables with insect eyes are not sprayed with pesticides.

How to reduce pesticide residues in vegetables?

The first trick: soaking.

You can soak the vegetables you bought for a few minutes before rinsing. Or you can soak the vegetables in rice washing water, which neutralizes the pesticide toxicity.

The second trick: wash the vegetables in salt water.

Wash the vegetables with 5% salt water.

The third trick: peeling.

Vegetables such as cucumbers and eggplants are generally used more pesticides, and vegetables and fruits such as Peijing can be peeled directly before eating.

The fourth trick: high temperature heating.

High-temperature heating can also decompose pesticides. Some heat-resistant vegetables, such as cauliflower, beans, celery, etc., can be washed and scalded with boiling water for a few minutes, which can reduce the amount of pesticides by 30%, and then 90% of pesticides can be removed by high-temperature cooking;

Fifth trick: sun exposure.

Sunlight exposure can decompose and destroy some pesticides in vegetables. It has been determined that the residue of pesticides such as organochlorine and organic mercury can be reduced by about 60% when vegetables are exposed to sunlight for 5 minutes.

Fruits and vegetables account for a large part of our daily diet, and many people who pursue a healthy life prefer to eat fruits and vegetables. However, as we all know, in the process of growing fruits and vegetables, in order to harvest better and make them look better, many people will spray a large number of pesticides on them to repel insects. These pesticides will also remain on the skin of fruits and vegetables.

If we consume these fruits and vegetables with pesticide residues, it will have an impact on our health. Therefore, how to remove the pesticides remaining on fruits and vegetables is particularly important.

Generally, there are four main ways to remove pesticides from fruits and vegetables, that is, blanching, peeling, frying, and cleaning. Among them, frying can remove 90% of the residual pesticides on fruits and vegetables, and blanching can also remove 80%. However, general fruits and vegetables are not suitable for frying, and after the food is fried, it will not only destroy the nutrients in it, but also have high calories and fat, which is not conducive to our health.

Blanching has less damage to the nutrients of vegetables and fruits, and is feasible for ordinary vegetables. However, some pesticides can even decompose into more toxic substances at high temperatures, so it is not a very safe way to cultivate.

Therefore, washing before eating or cooking is undoubtedly the most feasible way to remove pesticide residues. Some studies have found that the use of water, detergent and four special vegetable and fruit cleaning agents to clean vegetables and fruits, each of which will significantly reduce the residual pesticides, but the cleaning effect of using special fruit and vegetable cleaning agents is no different from cleaning with water. In general, washing fruits and vegetables in clean water can be effective.

This is because most pesticides are diluted in water and then sprayed on fruits and vegetables, so under normal circumstances, the fruits and vegetables can be cleaned by rubbing and washing by hand after soaking them in rented potato water for ten minutes.

On the other hand, if you are not sure whether to clean the pesticide residue on the surface of fruits and vegetables, you can peel off the outer skin before eating, although some nutrients will be lost, but it is a good idea from a safety point of view.

In addition, many people have such a misunderstanding, that is, they think that the appearance is not very good, and those with insect eyes have not been sprayed with pesticides, in fact, this is a wrong view, because this may be due to the scars left by spraying pesticides too late, and it does not mean that pesticides have not been sprayed.
